PLATFORM FOR TRUCKS.

SPECIFICATION forming part of Letters Patent No. 351,145, dated October19, 1886.

Application filed July 22, 1886. Serial No. 209,732.

To all whom it may concern:

Be it known that I, THOMAS WVRIGI-I'r, of Jersey City, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovement in Platforms for Trucks, of which the following is a full,clear, and exact description.

My invention relates to an improved construction of platform offour-wheeled vehicles; and the invention consists, principally, of theemployment of double inverted arch-bars for holding and supporting theforward ends of the cross-pieces of the platform, whereby the platformis made lighter and cheaper than ordinary platforms, and at the sametime stronger and less liable to sag.

The invention also consists of the construction, arrangement, andcombination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my new and improved truck-platform, showingthe axle-tree and the fifth-wheel. Fig. 2 is a front elevation of thesame, and 3 is a side view of the same.

A Arepresent the springs secured upon the axletree B in the usualmanner, and the rear ends of the springs are bent upward and se cured tothe rear bar, 0, in the usual manner. The forward ends of the springsare connected to the front metal bar or plate, D. Upon this plate D isplaced the arch-bar E, on which rest the forward ends of the severalcross-bars F F. The rear ends of these cross-bars are framed into therear bar, 0, in the usual manner. Upon the forward ends of thecross-bars F is placed the upper arch-bar, G. Both archbars are boltedor riveted at their ends to the front plate, D, and the springs A, anddown through the arch bars,the cross-piece F, and the front plate, D,are passed the heavy bolts H, 011 which are placed, between the lowerarch-bar and the front plate, D, the supporting-blocks I, which preventthe arch-bars and the front (No model.)

plate from springing when the nuts on the bolts are turned home. Theshort center piece, J, is framed into the crossbars F in the usualmanner, and in it is formed the king-bolt hole 6, and upon the bars F issecured the fifth wheel K, in the usual manner.

By constructing the forward part of the platform, as described, with thetwo arch-bars united by bolts to each other, and to the crossbars F andfront plate, D, and supported by the blocks 1, the platform is verycheaply made, and is comparatively light, and is very stiff and strong,so that the platform will not sag and cause binding of the truck at thefifthwheel in turning, which is a great difficulty now experienced withtrucks having a wooden front piece for supporting the forward ends ofthe bars F.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a truck-platform, the combination, with the bars F, of the bentarch-bar E, conneeting the side springs of the platform and supportingthe ends of the bars F, substantially as described.

2. In a truck-platform, the combination, with the bars F, of the twoarch-bars E G, between which the bars F are held, substantially asdescribed.

3. The combination, with the arch-bar E, bolts H, bars F, andsupporting-plate D, of the blocks I, placed upon the bolts H be tweenthe arch-bar and the plate D, substantially as described.

4. In a truck-platform, the two arch -bars E G, resting at their ends,upon the plate D and springs A, in combination with the crossbars F,held between the arclrbars, the blocks I, and the bolts H, the blocksbeing placed upon the bolts between the arch-bar E and plate D,substantially as described.
